Abstract: By means of static pyrocarbon-depositions, it was the aim to contribute to the understanding of the formation and the deposition of pyrocarbon. To achieve this target, a statistical test programme was applied, which enabled the reduction of the necessary individual trials to only 10 with coincident variation of three independant test-variables. The boundary layer over heated substrates in gaseous atmospheres, the Langmuirzone, was evaluated in various gases by optical means; the structure of the Langmuirzone could be defined. The combination of the results from structure evaluations and evaluations from the Langmuirzone led to a better understanding of the pyrolysis procedure; a hypothesis on this subject could be confirmed. A proposal was made to describe the structure of high density pyrocarbon completely. A method for planimetric evaluation of single film exposures was developed and applied. A procedure was also developed for coincident determination of the temperatures of two heated objects, and this method could be mathematically verified.
